EUGENE K. BEOKWI'IH, OF NIANTIO, CONNECTICUT, ASSIGNOR OF HALF TO GEORGE P. HILL, OF SAME PLACE,

COMBINED GAGE AND SQUARE.

SPECIFICATION forming part of Letters Patent No. 387,966, dated August 14, 1888.

Application tiled April 1Q, 1888. Serial No. 270,456. (No model.)

T0 all whom, it 'may concern:

Be it known that I, EUGENE K. BECKWITH, a citizen ol1 the United States of America, residing at Niantie, in the county of New London and State of Connecticut, have invented certain new and useful Improvemeutsin a Combined Gage and Square; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to the accom pau ying drawings, and to letters or tignres ot' reference marked thereon, which t'orm a part ot" this specification.

My invention relates to certain new and nselnl improvements in carpenters squares or gages, the object of the same being to provide an implement which can be advantageously used for laying oit1 lumber, to mark mortises, or for laying oft angles, bcvels, 85e. and it consists in the special construction and combination of the parts, as will be hereinai'ter fully1 set forth, and specifically pointed out in the claims.

In the accompanying drawings, Figure l is a side view of a gage or square constructed in accordance with my improvement. Fig. 2 is a plan View, and Fig. 3 an edge View.

The tool I am about to describe is preferably made np ol' steel, though other material may be employed; and it consists of the main portion A and member B, which entend at right angles with what I term the base or tlange77 (l. This flange is rigidly connected to the outer edge ot' the long arm ot' the implement. The main arm A, near its juncture with the arm or member B, has an opening, D, formed with jogs d d, connected to each other and resi-nnblng a series of steps, and beneath this opening D is a smaller one, E, one side of which is formed with an angle of forty-live degrees, while the opposite side makes an angle ot' seventy degrees, these different angles heilig used for laying off miters of different angles. Adjacent to the opening D the main arm A is formed with a rectanguiar opening, F.

The inner edge of the long arm of the implement is provided with a series of jogs, com

meneing at the member B and continuing down to the outer end of the arm, their edges having scale-marks thereon, as shown.

The flange C has a series ot' rectangular cntaway portions, c c, both for the purpose of lightening the instrument and permitting it to be placed upon a joist or other piece of lumber when marking.

7When it is desired to cnt mortiscs, the rect angular opening E is used, and the mark for the tenon is placed upon another piece of lumber by using the same opening as a markinggage. Then it is desired to mark mortises not of a standard size, the implement may be slid along the piece ot' timber until the proper indicative marks are reached. \Vhen two sides of the mortise or tenon have been marked, the implement is reversed. By proper manipulation et" the implement the proper gagemarks can be placed upon the lumber and the conlplete lines finished by using another portion of the gage.

In practice the implement will be of such a size that it can be used for marking lumber from seveneighths of an inch in thickness upward to the usual sizes, and theeut-away portions c c not only lighten the implement, but also permit of its being readily picked up when lying dat. Gagemarks are also placed on the tianges C C for marking distances,

l'Vhat I claim as new is- 1. As an improved article of manufacture, the device herein set forth, consisting of a square having a T-headed llange provided at intervals on opposite sides of its center with jogs c c, the arms A and member B, a mortiseopening, F, the opening l), havings jogs d d, and the ruiter-opening E, having walls of different angularity, substantially as described.

2. The combination, in a device for laying oft' lumber, of a square having a T-headed tlange, said tlange being provided at intervals on opposite sides of its center with jogs c c, substantially as shown.

In testimony whereof I alli); my signature in presence of two witnesses.
